• During 2014 and 2015, Cyclops spent a total of P459,000 in developing a new process that was patented (Patent A) on April 1, 2016; additional legal and other costs of P50,000 were incurred.

• A patent (Patent B) developed by Nanette Inventor, an inventor, was purchased for P187,500 on December 1, 2017, on which date it had an estimated useful life of 12 years.
